Both noise and notes are mixtures of sound waves at different frequencies.
A note is made up of a ripple pattern which repeats itself over and over again in an ‘ordered’ way.
While a noise is made up of individual ripples which have no relationship to each other and do not repeat - and so are ‘disordered’.
If an object moves, it causes a disturbance in the surrounding air which ripples out as soundwaves. If the object vibrates with a fast and repeating pattern, like a string, then the sound waves will be evenly-spaced and regular; that is, the air particles are squeezed together into evenly-spaced waves. These evenly-spaced, regular sound waves are heard as notes with distinct pitches.
But, if you drop a vase or slam a door shut, you hear a noise which is made up of a lot of unrelated frequencies with no repeating pattern - and so will be a heard as noise with no defined pitch.
To be a note, it doesn’t really matter how complicated the individual ripples are, as long as the pattern repeats itself.

It's very rare to find Music theory explained in informative and interesting way; thanks and looking for more.
This isn’t music theory, it’s acoustics.
This is pure gold. Just knowladge, just a perfect video to understand music. Congratulations.
Little did I know I was learning about notes in my bath tub at the age of 5
Man, you should talk Sal Kahn. The world needs to be exposed to your work. Genuine hero.
I LOVE YOU WHO MADE THIS VIDEO. Just what I needed!
Excellent video. Clear, informative, and nicely put together with the visual and audio effects. Thankyou very much.
Thanks, mate.
Great video! Looking forward for the next one.
Cheers :)
5:53 that's why when i don't have an amp lean my guitar's headstock to onto my room's door. a natural amplifier!
I wish this had more views. Such great content!
the part with the skull was hilarious! xD
You have truly amazing material, thanks a lot.
2:05 This is also how we hear voiced fricatives. Voice=note, friction=noise.
Very helpful for me the visualisation at 2:48 (the water-Waveform -Relationship) THX
No problem. Thanks for the comment :)
great video, love your effort to educate people
Super video, thank you!!
this is the most underrated series ever, homies drenched his bathroom for us
Tesla... Sound, vibration, energy
Its ALLLLL right here. Well done
the vibration of your skull - rofl! Excellent stuff, man, thanks for the education!!
You are great man😍
Do you ever create bad videos? haha
As always, really clear explanations and you really get to the point, thanks again for your vids!
Thanks, mate :)
Awesome, really interesting! :)
Thank you for this video! it is really interesting ,and helpful:D
Thanks, mate.
great videos my dude :)
Ahhhh the bathtub example is so brilliant!
It there a video that teaches point source/line source?
so at 7:15 area when talking about nodes, and it shows the wave moving with nodes pointed with arrows, is that like a guitar string or the sound wave the instrument is making. I know you said nodes included the ends of the guitar string but I'm trying to figure out how there could be other nodes on a string besides them. Wouldn't it be moving up and down all at the same rate? You said standing wave as well, so I'm just not sure. At any rate these videos are excellent and appreciate you making them. Like the simplicity and quickness. Helped me learn a lot just from searching one question lol
omg, now I'm going to try to break down pattern in the noises I hear to see if there is music within noises.
The concept of the tuning fork and “noise-canceling” headphones. Is this how Apple & co. do it?
if my physics teacher had let me see this video, I would not have failed the harmonic motion class
캬~ 진짜 명쾌하고 심플한 설명이다
this is great
😮 amazing
04:35 great demonstratiom 😁
very interesting
Your bathroom floor though.
A sacrifice to the channel.
@@WalkThatBass wipping out tons of water with rugs? must have been nice ;)
2:00 This makes noise sound easy to get rid of (algorithmically)
yeah... Do u work with that?
This is test explanation ive foud.
6:15 that's pretty cool.
idk why I watched this but Im wiser now
Good evening
Great video! I have a question. Does a instrument is designed to amplifie its natural frequency? (shape, size, material, etc) I mean, when you play a notes will you always create resonance?
Yo that bee scared the shit of me I jumped like 10 feet
SAME! 🤣
Noise = Indefinite pitch
Note = Definite pitch
A noise sounds like it has pitch
coool😜
That water does not look clean...
Who is put here form school during quarantine
Did you take a bath after that video 😂
i would think the difference between a note and a noise is the same as the difference between a plant and a weed. noises and weeds are unwanted, unappreciated, unplanned. so it would really kind of depend who you ask...based on their opinion.
theres even euphamistic terms for each. a weed that produces good things is called a volunteer. and a noise that is musical is called musique concrête. (mew-zeek kon-cray)
JAJAJAJAJAJ 777likes pero madre mia vegetini
i watched this bc im deaf lol
super sir can i have your name and number sir
